Adjust function definitions in kern_resource.c to avoid clang 15 warnings
With clang 15, the following -Werror warnings are produced:
sys/kern/kern_resource.c:1212:10: error: a function declaration without a prototype is deprecated in all versions of C [-Werror,-Wstrict-prototypes] lim_alloc() ^ void sys/kern/kern_resource.c:1365:11: error: a function declaration without a prototype is deprecated in all versions of C [-Werror,-Wstrict-prototypes] uihashinit() ^ void
This is because lim_alloc() and uihashinit() are declared with (void)
argument lists, but defined with empty argument lists. Make the
definitions match the declarations.
